Coordination compounds containing bis-di­thiol­ene-chelated molybdenum(IV) and oxalate: comparison of terminal with bridging oxalate

[Mo(tfd)₂(ox)]²⁻ as tetra-n-butyl­ammonium salt [co-crystal with oxalic acid and chloro­form; tfd is S₂C₂(CF₃)₂ and ox is C₂O₄] and [(tfd)₂Mo(μ-ox)Mo(tfd)₂]²⁻ as tetra-n-butyl­ammonium salt.

Abstract

Two coordination compounds containing tetra-n-butyl­ammonium cations and bis-tfd-chelated molybdenum(IV) [tfd²⁻ = S₂C₂(CF₃)₂ ²⁻] and oxalate (ox²⁻, C₂O₄ ²⁻) in complex anions are reported, namely bis­(tetra-n-butyl­ammonium) bis­(1,1,1,4,4,4-hexa­fluoro­but-2-ene-2,3-di­thiol­ato)oxalatomolybdate(IV)–chloro­form–oxalic acid (1/1/1), (C₁₆H₃₆N)₂[Mo(C₄F₆S₂)₂(C₂O₄)]·CHCl₃·C₂H₂O₄ or (NⁿBu₄)₂[Mo(tfd)₂(ox)]·CHCl₃·C₂H₂O₄, and bis­(tetra-n-butyl­ammonium) μ-oxalato-bis­[bis­(1,1,1,4,4,4-hexa­fluoro­but-2-ene-2,3-di­thiol­ato)molybdate(IV)], (C₁₆H₃₆N)₂[Mo₂(C₄F₆S₂)₄(C₂O₄)] or (NⁿBu₄)₂[(tfd)₂Mo(μ-ox)Mo(tfd)₂]. They contain a terminal oxalate ligand in the first compound and a bridging oxalate ligand in the second compound. Anion 1 ²⁻ is [Mo(tfd)₂(ox)]²⁻ and anion 2 ²⁻, formally generated by adding a Mo(tfd)₂ fragment onto 1 ²⁻, is [(tfd)₂Mo(μ-ox)Mo(tfd)₂]²⁻. The crystalline material containing 1 ²⁻ is (NⁿBu₄)₂-1·CHCl₃·oxH₂, while the material containing 2 ²⁻ is (NⁿBu₄)₂-2. Anion 2 ²⁻ lies across an inversion centre. The complex anions afford a rare opportunity to compare terminal oxalate with bridging oxalate, coordinated to the same metal fragment, here (tfd)₂Mo^IV. C—O bond-length alternation is observed for the terminal oxalate ligand in 1 ²⁻: the difference between the C—O bond length involving the metal-coordinating O atom and the C—O bond length involving the uncoordinating O atom is 0.044 (12) Å. This bond-length alternation is significant but is smaller than the bond-length alternation observed for oxalic acid in the co-crystallized oxalic acid in (NⁿBu₄)₂-1·CHCl₃·oxH₂, where a difference (for C=O versus C—OH) of 0.117 (14) Å was observed. In the bridging oxalate ligand in 2 ²⁻, the C—O bond lengths are equalized, within the error margin of one bond-length determination (0.006 Å). It is concluded that oxalic acid contains a localized π-system in its carb­oxy­lic acid groups, that the bridging oxalate ligand in 2 ²⁻ contains a delocalized π-system and that the terminal oxalate ligand in 1 ²⁻ contains an only partially localized π-system. In (NⁿBu₄)₂-1·CHCl₃·oxH₂, the F atoms of two of the –CF₃ groups in 1 ²⁻ are disordered over two sets of sites, as are the N and eight of the C atoms of one of the NⁿBu₄ cations. In (NⁿBu₄)₂-2, the whole of the unique NⁿBu₄ ⁺ cation is disordered over two sets of sites. Also, in (NⁿBu₄)₂-2, a region of disordered electron density was treated with the SQUEEZE routine in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9–18].

Chemical context  

The oxalate (ox²⁻, C₂O₄ ²⁻) ion is a very useful ligand in transition metal chemistry. Its usefulness stems in part from its ability to act as a chelate ligand toward a metal cation while retaining two more O atoms with the ability to donate to another metal cation. Thus, while coordination compounds containing terminal oxalate are known, oxalates can easily act as bridging ligands to allow for the synthesis of dimetallic and multimetallic mol­ecular compounds, as well as extended coordination polymers (Clemente-León et al., 2011 ▸; Gruselle et al., 2006 ▸). Most of the work has involved V, Cr, Mn, Fe, Co, Ni and Cu, as well as Ru and Rh. Compounds where oxalate coordinates to molybdenum are rare, although some examples have been synthesized, mostly in the context of nitro­genase models, where oxalate was deemed a model for homocitrate (Demadis & Coucouvanis, 1995 ▸). Stimulated by our previous results on the molybdenum(IV) di­thiol­ene fragment Mo(tfd)₂ [tfd²⁻ = S₂C₂(CF₃)₂ ²⁻] with a labile ‘cap’ (Harrison et al., 2007 ▸; Nguyen et al., 2010 ▸), we added oxalate to the Mo(tfd)₂ fragment, as described in the ‘Synthesis and crystallization’ section (§5). The [Mo(tfd)₂(ox)]²⁻ (1 ²⁻) and [(tfd)₂Mo(μ-ox)Mo(tfd)₂]²⁻ (2 ²⁻) anions were indeed obtained, offering an opportunity for a structural comparison.

Structural commentary  

The counter-cation for both complex molybdate anions was tetra-n-butyl­ammonium. 1 ²⁻ was obtained as (NⁿBu₄)₂-1·CHCl₃·oxH₂, while 2 ²⁻ was obtained as (NⁿBu₄)₂-2. The mol­ecular structure of 1 ²⁻ is shown in Fig. 1 ▸, where NⁿBu₄ ⁺ counter-ions and co-crystallized oxalic acid, as well as chloro­form solvent mol­ecules, are not shown. Only one orientiation is shown for the disordered tri­fluoro­methyl groups involving atoms C7 and C8. The charge on the molybdenum-containing moiety, which is identified as 1 ²⁻, is unambiguous, due to the tetra-n-butyl­ammonium cations. While tfd can be redox-non-innocent (Hosking et al., 2009 ▸), it is redox-innocent here. The C—C bond lengths in the two tfd ligand backbones [1.349 (8) Å for C1—C2 and 1.353 (8) Å for C5—C6] are a clear indication of fully reduced (dianionic) ene–di­thiol­ate (tfd²⁻), such that the oxidation state of the metal is +IV. The Mo—S bond lengths, ranging from 2.3265 (14) to 2.3390 (15) Å, are as expected for tfd complexes of Mo^IV (Nguyen et al., 2010 ▸). Regarding the bonded oxalate, the average Mo—O bond length is 2.12 Å [Mo1—O1 = 2.104 (3) Å and Mo1—O2 = 2.135 (3) Å]. Within the oxalate unit, the chemically distinct O atoms (coordinating to molybdenum versus uncoordinating) show different bond lengths to the directly bonded C atom. The C—O bond length involving the metal-coordinating O atom is 1.276 (6) Å (average of two values), with the C—O bond length involving the uncoordinating O atom is 1.232 (6) Å (average of two values), for a difference of 0.044 (12) Å. While it may be tempting to describe the longer C—O bond as a single bond and the shorter C—O bond as a double bond, such a description would not be fully accurate since the bond-length alternation is only partial and less pronounced than for oxalic acid. The oxalic acid (oxH₂) mol­ecule found in the structure of (NⁿBu₄)₂-1·CHCl₃·oxH₂ is shown in Fig. 2 ▸. This oxalic acid mol­ecule exhibits stronger bond-length alternation: a difference (for C=O versus C—OH) of 0.117 (14) Å is observed. For further comparison, the structure of 2 ²⁻, in (NⁿBu₄)₂-2, is valuable. Both 2 ²⁻ and the (disordered) tetra-n-butyl­ammonium ion in the structure of (NⁿBu₄)₂-2 are shown in Fig. 3 ▸. For the bridging oxalate ligand in 2 ²⁻, bond-length equalization is observed, within the error margin of one bond-length determination (0.006 Å). The details of the oxalate substructure are shown in Fig. 4 ▸, where Fig. 4 ▸(a) highlights the bond-length changes on going from a terminal oxalate in 1 ²⁻ to a bridging oxalate in 2 ²⁻, where parameters related to chemically equivalent bonds are averaged for clarity, and Fig. 4 ▸(b) shows all data before averaging. Fig. 4 ▸(c) shows the bond lengths in the free oxalic acid mol­ecule in (NⁿBu₄)₂-1·CHCl₃·oxH₂. Fig. 4 ▸(d) summarizes the findings: oxalic acid contains a localized π-system in its carb­oxy­lic acid groups, the bridging oxalate in 2 ²⁻ contains a delocalized π-system and terminal oxalate in 1 ²⁻ contains a partially localized π-system. While only marginally significant (ca 1σ), an effect involving the C—C bonds of oxalate can be seen: upon becoming bridging, the oxalate C—C bond shortens from 1.528 (7) Å to 1.51 (1) Å (Figs. 4 ▸ a and 4b). While this bond shortening may initially be surprising, it is actually theoretically expected: the π-system in a localized butadiene-like system is anti­bonding with respect to the central C—C bond. When oxalate becomes bridging, due to delocalization in the π-system, the electronic structure is no longer butadiene-like but rather resembles two allyl anions linked at the central C atom, where the π-overlap at the central C atoms is not anti­bonding but just nonbonding. Apart from the specifics of the oxalate substructure in 2 ²⁻, there are no dramatic changes in the coordination sphere of molybdenum on going from 1 ²⁻ to 2 ²⁻. The points made above for 1 ²⁻ related to Mo—S bond lengths (normal) and C—C bond lengths in the tfd ligand (double bond) typically apply also to 2 ²⁻. Also, both metal centres much more closely resemble a trigonal prismatic structure than an octa­hedral structure, as is expected for d ² tris-chelates involving di­thiol­enes. Using the X—M—X_trans criterion (Beswick et al., 2004 ▸; Nguyen et al., 2010 ▸), the geometry around molybdenum in 1 ²⁻ is 88% trigonal-prismatic. Using the same method, the geometry around molybdenum in 2 ²⁻ analyzes as 99% trigonal-prismatic.

Supra­molecular features  

The oxalic acid solvent molecule and the metal-coordinating oxalate ligand in (NⁿBu₄)₂-1·CHCl₃·oxH₂ form a hydrogen-bonded network (Table 1 ▸). The oxalate O atoms of 1 ²⁻ that are not metal coordinating act as hydrogen-bond acceptors. Oxalic acid acts as a hydrogen-bond donor: both of its OH functionalities hydrogen bond to two different mol­ecules of 1 ²⁻, such that infinite chains along [100] of the type ‘—1 ²⁻—HOOC-COOH—1 ²⁻—, etc’ are formed. The (NⁿBu₄)₂ ⁺ cations (one of them containing disorder) are packed around the 1 ²⁻ anion, along with a CHCl₃ solvent mol­ecule that forms part of the structure. A plot showing anisotropic displacement ellipsoids for all non-H atoms (including disordered ones) in (NⁿBu₄)₂-1·CHCl₃·oxH₂ is shown in Fig. 5 ▸. In contrast, there are no hydrogen bonds or notable close contacts in the structure of (NⁿBu₄)₂-2, which consists of a packing of 2 ²⁻ anions and NⁿBu₄ ⁺ cations, both of which are shown in Fig. 3 ▸.

Database survey  

Relevant coordination compounds containing di­thiol­enes are discussed above, where review articles for coordinating oxalate are also referenced. A search of the Cambridge Structural Database (Version 5.38, including updates up to May 2017; Groom et al., 2016 ▸) reveals no reports of molybdenum dithiolene complexes that contain oxalate.

Synthesis and crystallization  

General specifications  

All manipulations involving metal-containing compounds were carried out under an inert (N₂) atmosphere using standard glove-box (M. Braun UniLab) and Schlenk techniques. Solvents were purified prior to use by vacuum distillation from mol­ecular sieves. Organic and inorganic starting materials were obtained from Sigma–Aldrich. Mo(tfd)₂(tht)₂ (tht = tetra­hydro­thio­phene) was synthesized from Mo(tfd)₂(bdt) (bdt = S₂C₆H₄) as in Nguyen et al. (2010 ▸). Mo(tfd)₂(bdt) was synthesized as in Harrison et al. (2007 ▸). Tetra-n-butyl­ammonium oxalate was prepared by neutralizing oxalic acid with aqueous tetra­butyl­ammonium hydroxide, followed by drying under vacuum at 333 K.

Synthesis of (NⁿBu₄)₂-1.CHCl₃·oxH₂  

We were unable to obtain 1 ²⁻ as the only molybdenum product produced in a reaction. Attempts always led to significant decomposition to form a blue material, almost certainly molybdenum that is reduced below the oxidation state +IV due to the reducing power of oxalate. However, 1 ²⁻ can be obtained as crystals (co-crystals with oxalic acid and chloro­form) in the form of brown blocks. 2 mg of Mo(tfd)₂(bdt) (2.9 µmol) were dissolved in a small amount of chloro­form in a glass vial. In a second glass vial, 16.7 mg (29 µmol) of tetra-n-butyl­ammonium oxalate were dissolved in the amount of chloro­form needed to create a clear solution. The contents of the two vials were mixed and 3.3 µl (14.6 µmol) of bis­(tri­methyl­sil­yl)acetyl­ene, needed to labilize the bdt fragment (Nguyen et al., 2010 ▸), were added via microlitre syringe. The initially dark (blue–green) solution became lighter, and small brown particles began to form. After 72 h, the solvent was reduced under vacuum, and orange–brown crystals grew. Blue–green needles (not of X-ray quality) of a different (likely reduced) molybdenum product were also growing. The orange–brown blocks were manually separated and chosen for X-ray crystallography.

Synthesis of (NⁿBu₄)₂-2  

2 mg (2.8 µmol) of Mo(tfd)₂(tht)₂ were dissolved in a minimal amount of chloro­form. A solution of 16 mg (28 µmol) of tetra-n-butyl­ammonium oxalate in 2 ml of chloro­form was added. The solution turned red and, after 2 h, thin pink rectangular crystals had formed. The liquid was deca­nted and the crystals were washed twice with chloro­form and dried under vacuum. X-ray-quality crystals were grown using vapour diffusion. In a small vial, the product was dissolved in di­chloro­methane. The small vial was placed uncapped into a larger vial with chloro­form. The larger vial was capped, and over a period of 2 d, the di­chloro­methane solvent had evaporated from the small vial and dissolved in the chloro­form in the larger vial, leaving pink crystals in the smaller vial. The crystals were found to be very air-sensitive, and exposure to air leads to decomposition to form a liquid that colours the surface of the crystals initially green and later blue.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. In (NⁿBu₄)₂-1·CHCl₃·oxH₂, H atoms bonded to C atoms were placed in calculated positions and included in a riding-motion approximation, while H atoms bonded to O atoms were refined independently with isotropic displacement parameters. In the anion 1 ²⁻, atoms F7/F8/F9 were included as disordered over two sets of sites, with refined occupancies of 0.58 (2) and 0.42 (2). Atoms F10/F11/F12 were included as disordered, with refined occupancies of 0.502 (10) and 0.498 (10). The C—F bond lengths and F⋯F distances were restrained using the SADI command in SHELXL (Sheldrick, 2015 ▸) and the anisotropic displacement parameters of the disordered F atoms and bonded C atoms were restrained using the SIMU command. In addition, the N and 8 C atoms (C29–C36) of one of the independent NⁿBu₄ ⁺ cations were refined as disordered over two sets of sites, with refined occupancies of 0.676 (9) and 0.324 (9). The SAME command in SHELXL was used to restrain the geometry of the disordered C-atom chains to those of the ordered NⁿBu₄ ⁺ cation and the SIMU command was used to restrain anisotropic displacement parameters of the disordered atoms. In (NⁿBu₄)₂-2, all H atoms were placed in calculated positions and refined in a riding-motion approximation. During the refinement of the structure of (NⁿBu₄)₂-2, electron-density peaks were located that were believed to be highly disordered solvent mol­ecules (crystallization solvents were CH₂Cl₂/CHCl₃). Attempts made to model the solvent mol­ecule were not successful. The SQUEEZE (Spek, 2015 ▸) option in PLATON (Spek, 2009 ▸) indicated that there was a large solvent cavity of 156 Å. In the final cycles of refinement, this contribution of 62.6 electrons to the electron density was removed from the observed data. The density, the F(000) value, the mol­ecular weight and the formula are given without taking into account the results obtained with the SQUEEZE option. Similar treatments of disordered solvent mol­ecules were carried out by Stähler et al. (2001 ▸), Cox et al. (2003 ▸), Mohamed et al. (2003 ▸) and Athimoolam et al. (2005 ▸). Also in (NⁿBu₄)₂-2, the whole mol­ecule of the unique NⁿBu₄ ⁺ cation was included as disordered over two sets of sites, with refined occupancies of 0.589 (6) and 0.411 (6). The same command in SHELXL was used to restrain the geometry of the minor component of disorder to that of the major component and the SIMU command was used to restrain all anisotropic diplacement parameters of the disordered atoms.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
